Front Suspension "kit" for 1 ton?? - The 1947 - Present Chevrolet & GMC Truck Message Board Network

tow guys · 01-14-2011, 06:10 PM

We're getting ready to pull the front suspension apart on our 70 GMC 1 ton and was wondering if any or all of the parts from the 1/2 ton kit is the same as our 1 ton truck? I can't seem to find any kits for the 1 ton and some of the parts do seem to carry the same part #.
Any help would be most appreciated.
Thanks,
Tony

Everything should be the same. Only thing I would maybe change is the size/thickness of the bags.

Depends on what you mean by "kit". As Jason said, I would use a Slam 8" front bag, but the plates and cup are the same on my C20 as my C10 was.

I know there are frame differences, but if you are just swapping the coils for bags, then it's the same gear.

Are you talking air ride kits or rebuild kits?
(as in bushings, balljoints, and tie rod ends)

I was referring to rebuild kit as in ball joints etc. This is a tow truck so air suspension is probably out of the question

I assume your truck is still has drum brakes up front.
Most auto parts stores have the parts, or should be able to order them.
(alot of 67-72 parts aren't "in stock",... because there's not much demand for them)
The lower balljoints are definitely bigger on the 3/4 and 1-ton trucks because the hole in the lower a-arm is larger than the 1/2 ton version.
Tie rods should also be bigger.

If you can't find parts locally,... I would look at Early Classic Enterprises. (ECE)

Are the 1 ton parts the same as the 3/4 ton trucks? I can't seem to find any front end parts listed for 1 ton, just 1/2 or 3/4. Very confused.....

I would shop for 3/4-ton parts.
The 73-87 3/4-ton and 1-ton parts share balljoint and tie rod part numbers.
I assume the older 67-72 C20 and C30 truck would also.

Maybe someone else can add some info?

I am pretty sure the ball joints and tie rods are the same. Not sure on the controll arm shafts.
